In addition to the relation between the precipitation amount and low-cloud properties and contribution of meteorological factors on the surface shortwave irradiance variation obtained from conventional passive satellite sensors, recent data from active satellite sensors revealed the behaviors, similarities and differences in the transition among cloud droplets, drizzle and precipitation particles over China and the Amazon from the analyses of cloud vertical profiles and the radar reflectivity. Moreover, the numerical modeling illustrated that the difference in statistical behaviors between the optical depth and effective particle size was caused mainly by the difference in shapes of aerosol size spectra.

除了传统无源卫星传感器获得的降水量与低云特性之间的关系以及气象因素对表面短波辐照度变化的贡献之外，有源卫星传感器的最新数据还揭示了云间转换的行为、异同通过云垂直剖面和雷达反射率分析，了解中国和亚马逊地区的水滴、毛毛雨和降水颗粒。此外，数值模拟表明，光学深度和有效粒径之间统计行为的差异主要是由气溶胶粒径谱形状的差异引起的。
